As the final votes are tallied and Democrats continue to notch midterm election victories this week, Republican incumbents were toppled in New Jersey and California by opponents who built campaigns focused on affordable and accessible health care.

Former Obama administration official Andy Kim was officially declared the winner in New Jersey’s 3rd district Wednesday, ousting Rep. Tom MacArthur (R-NJ). MacArthur was one of the left’s biggest health care foes, and earned the label as “the face of the GOP’s health care repeal” by the health care advocacy group Protect Our Care, as Bloomberg noted.

Last year, MacArthur worked with Freedom Caucus Chairman Mark Meadows on an amendment to the GOP’s bill to repeal the Affordable Care Act (ACA) that would have allowed insurance companies to discriminate against people with pre-existing conditions, which ultimately passed the House.
